ADJUSTABLE TONGUE.'

madam.

To allI whom it may concern: l Be it known that I, PAUL HANsMaNN, a citizen of the United States. residing at Long Prairie, inthe county of Todd and State of Minnesota, have invented certain new and useful Improvements in Adjustable Tongues,of which the following is a specitication.

My invention relates'to improvements in adjustable couplings designed particularly for connecting a pluralityof stripper harvesters, binders or similar machines to an engine.. :whereby they are drawn alo`ng ben hinduthe"v engine each in a different path so as toccut different swaths.

To t-hisfend my invention consists of inipro-ved vmeans for adjusting the tongue of the Amachine hereinafter more particularly set forth and described.

In the accompanying drawings forming' part of this specification, Figure l is a perspective view *ofv a portion of the front end of a hinder'and connected tongue fitted with work of the machine to be .drawn and B the my improvements, Fig. 2 is al plan view of the tongue and support embodying my improvements, Fig. 3 is a side'elevation of the partsshownin Fig. 2, and Fig. 4f is a-perspective view of `aufscrew shaft support form- .ing'part of my ii'iv'venticn.

Inl the drawings A represents the frametongue. The tongue B has pivotal support on'a cross bar 2 by means of a pin 3 passing through the cross bar and through the straps ltexteuding rearwardly from the tgpand botto-ni faces of the tongue. The crbss'bar 2 may have vertical swinging connection 5 withthe machine in line with the tongue and be further braced by means of a hook 6 carried by the inner end of the cro-ss bar and fastened through an eye 7 in a portion of the' vehicle construction. The cross bar carries a fixed tongue 8 extending in normal position of the parts forwardly in line with the pivotally supported tongue The end of the fixed `tongue 8 is? connected with the outer or longer end of the cross bar by curved track bars 9, the opposite 'sideiif the fixed tong-ue being preferably co nected with the inner end of the cross ha y a strap 10. y

In order to swing the tongue upon its pivot ytoward and away from the outer end of the Vcross bar. I provide the following mechanism. Secured Ato the inner side of the forward end ofthe fixed vtongue 8 is a speciagatin of Letters raient. Application led November 30., 1908. Serial I/To. 465,286. i

bracket 1l within which the shaft 12 has journal support, the outer end of the shaft having universal joint connection 13 with the screw shaft 14. The free end of the screw shaft" -14 extends through, and has threaded engagement with, a. nut 15, said knut having pivotal support 16 in the plates 4. In order to turn the shaft 12 from the machine I provide the sprocket 17 secured upon the shaft and having chain connection 18 with a sprocket 19 supported adjacent to the drivers seat 20 and being provided with a suitable actuating handle 21.

It will be apparent that by means ofthe forwardly extending element 8 I secure a fixed base for the adjusting screw at a pointforward of the pivotal support of.. the tongue. This permits a thrust or pull heing 'exerted upon the tongue transversely of its length and the fixed base givesa stationary support fo-r the hand actuated driving means leading to the machine. shaft 11 has a positive dri-ving connection with the tongue and I'use the word Cscrew as describing an element of mechanism having an equivalent positivejdriving connection with the tongue.

tongue so that vthe machine will travel at one side of the machine in front it is only necessary for the driver to turn the handle 2l. the necessary number of revolutions. This will turn the shaft l2 through the medium of the sprocket chain turning the screw li and causing the nut l5 to travel outwardly upon the screw; carrying'with it the tongue I5. The pivotal connection 13 between the screw and shaft .12 and the pivotal support 1G for the nut compensates-for the varying position of the screw. The curved hars 9 forni a supporting track for the tongue B during its adjustment. In carrying the tongue hack to normal position it is only necessarvto oppositelv' turn the shaft '19.' through the medium ofthe handie Q1. i j

i iv invention is designed particularly for use in drawingstripper harvesters one be hind the other across a field wherebyeach succeeding machine may cut a swath outside the swath cut by the next forward machine. The tongue being only adjustable away from The screw one sideof normal position I aiu enabled to'A secure a construction particularly strong and snnpleand with the advantage of being adjustablefrom the drivers seat.
